If you can move the cursor but the touchpad doesn't recognise the tap-to-click feature, it is possible that the tap-to-click feature is disabled.
To enable this feature, you need to have the touchpad driver installed. You can download the driver from your laptop manufacturer's website, after you enter your laptop's model number and the Windows version and System type (32-bit and 64-bit).
To enable the tap-to-click feature:
Start -> Control Panel -> (Hardware and Sound) -> Mouse -> Select the touchpad tab -> Enable the Touchpad Buttons (or Touchpad Enable, or a similar title)
System Preferences -> Trackpad -> Point & Click -> check the box next to Tap to click
Note: You can find your laptop's model number in System Information (Start -> All programs -> Accessories -> System tools -> System Information) or in the System window (right-click on My computer (This PC) -> Properties)
